Patent GB-2086745-A (GB)
Title: Gas diffuser
IPC: C02F3/20
Filed: 1981-05-11
Abstract: A gas diffuser for use in aerobic sewage treatment includes a valve device operable to seal the interior of the diffuser from a gas supply pipe whenever the pressure of gas in the pipe is below a predetermined level, increase in the gas pressure above the predetermined level causing the valve to open. The amount by which the valve opens is dependent upon the pressure of gas in the supply pipe. In one embodiment the valve comprises an inlet port one end of which is closed by a ball held there by gravity until lifted by the pressure of gas applied to the inlet port. The sides of the bore in which the ball rises with increasing gas pressure may diverge along the length of the bore away from the inlet port. In an alternative arrangement the walls of the bore are slotted. Alternatively, the valve member may comprises an inlet port coupled to a member having flexible walls which normally close the inlet port and which flex to open the port when the pressure applied to the inlet port exceeds the predetermined level. <IMAGE>

Title: Integrated circuits
IPC: H01L21/3205
Filed: 1981-07-23
Abstract: The invention relates to a concept of metallisation for the production of integrated circuit devices in which the components of the integrated circuit are arranged in cells (17) which are all identical, non-functional and assembled in a matrix (14). Components of adjacent cells are interconnected by a metallic sub-network (22) forming blocks (23: 231...2315) representing predetermined logic functions. The blocks (23) have input-output terminals (26) at predetermined points, by which they are interconnected by a metallic sub-network (24:241...). The cells and blocks each have a symmetry with respect to the two axes of the matrix, so that the metallisation is minimal and the distribution may be more concentrated. The invention is applicable more particularly to LSI devices. <IMAGE>

Title: Flexible sheet with fixing device
Inventor: PRICE DAVID GEORGE
IPC: F16B5/06
Filed: 1982-06-24
Abstract: A weatherproof sheet 1, for example a tarpaulin, has attached thereto one or more apertured fixing devices which may take the form of a plastics cleat 2, Fig. 1 or a plastics eyelet 8, Fig. 3.

Title: Atomic absorption spectrophotometer
Inventor: STOCKDALE TREVOR JOHN
IPC: G01N21/31
Filed: 1983-06-06
Abstract: An atomic absorption spectrophotometer uses optically encoded hollow cathode lamp assemblies (HCL1-HCL4). The code represents one or more atomic elements corresponding to their resonant line(s), and is read by corresponding optical code readers (OCR1-OCR4) whose outputs are fed to a microcomputer (MCP), which includes a microprocessor ( mu P) a read-only memory (ROM) and a read-write memory (RAM), to identify the elements. The read only memory (ROM) contains wavelength information at a location associated with each element by means of which the microprocessor causes the correct operating current to be supplied by the lamp power supply (LPS) and causes the monochromator (MN) to be driven to the appropriate wavelength by the monochromator wavelength control (MWC). The optical code may be for example a bar code and may be directly affixed to the lamp envelope or on a separate card attached to the lamp, the card being inserted into a card reader. <IMAGE>

Title: Separating particles from leakage gas flows
Inventor: HAGEMEISTER KLAUS
IPC: F16J15/447
Filed: 1984-07-20
Abstract: The device (1) incorporates a gap, formed between a wall (3) of a stationary part (2) of the turbo-machine and facing wall (5) on a rotating part (4) of the machine, which extends generally radially and through which gas flow from an adjacent region leaks. In order to avoid foreign particles passing into that region in the reverse gas flow which is induced along the stationary wall (3), that wall is provided with projecting edges (10) directed towards the rotating wall (5) which have the effect of breaking up the reverse flow into eddies which carry the particles into the turbulent flow adjacent the rotating wall from where they are led outwards by centrifugal action. The projecting edges (10) may be formed by equally and oppositely inclined wall surfaces (6 and 7) though in other embodiments the profile may be of saw-tooth or other form. Radial or radially inclined channels and/or projections may be provided on the rotating wall to provide outflow passages for the separated particles. <IMAGE>

Title: Apparatus and method for degrading antimistic fuel
Inventor: COFFINBERRY GEORGE ALBERT
IPC: F02M29/04
Filed: 1984-12-06
Abstract: The present invention relates to the degradation of antimisting fuel. Such fuel is to termed because it contains an additive which tends to inhibit the formation of a mist. One reason for using such an additive is to increase fire safety in the event of fuel spillage, as in accidental spillage of aviation fuel. The invention accelerates the fuel to restore the misting properties of the fuel. Applicant believes that the restoration involves the breakup of the reticulated structure formed by the additive. The apparatus may contain a single orifice 9, Fig. 1 or a baffle with a plurality of holes, Fig. 4. The plurality of holes may be blocked by a piston member, Fig. 10. <IMAGE>

Title: Flame-retardant cross-linked composition and flame-retardant cable using same
Inventor: HASEGAWA MASATAKE
IPC: C08L43/04
Filed: 1985-03-05
Abstract: The flame-retardant cross-linked composition is produced by mixing a first compound of a metallic hydrate and a halogen-free vinyl resin, such as a polyolefin or polyacrylate resin, with a silane-grafted halogen-free vinyl resin to form a second compound; and silane cross-linking the second compound. The metallic hydrate is used in an amount of about 50 to about 200 parts by weight per 100 parts by weight of the resins comprising 20-80 parts of the silane-grafted resin and 80-20 parts of the non- grafted resin. The composition is excellent in flame retardancy, thermal resistance and forming property, has reduced production cost as compared to conventional flame-retardant compositions, and does not produce any toxic gas such as hydrogen halide gas or halogen gas when burned. This composition is hence particularly useful for the sheath and the insulation of flame-retardant electric wires, cables and the like.
